.111 no \r glne spec 1 rsey, have invented or improvements in tlas- 11 oi WlllCll the ltollovving 1s a and uscil'nl tachnients. licaticn.

This invention has relation to improvements in internal combustionengines and the nature and objects thereof will be read ily apparent tothose skilled in the art to which it apportains, inthc light ol': thefolloivh description. oil the acconipanayingr drau n illustrating what lnova believe to he the preferred GllllJUtlllrlBIli; or l'ilotlltlll calexpression my invention from among other forms and arrangements Withinthe spirit thereof and the scope oi the appended claim.

itn object ot the invention is to n'ovide means for introchicing aqueousvapor into the manifold, intake or cylinders of an internal combustionengine, accompanied simultaneously With a predetermined proper tion 01air.

Another object of the invention is to provide a device of the characterabove set forth embodying means for regulating in dependent of eachother the amount of aqueous vapor and air, and to permitthe regulationof said means so as to vary the relative proportions of vapor and airadmitted.

it still further object of the invention is to provide a device of thecharacter de scribed designed to and capable of rendering; a moreeconomical operation. of the engine by incur-in the proper combustion ofthe :liuel, there 7 resulting in a saving of the amount of fuel consumedper unit of energy developed, and by preventing the formation oi?carbon, as Well as other uses and advantages which will become apparentas the nature of the device is more readily unden stood.

n re county oil Morris and tfltate throughout the several views in whichthey appear,

Figure l is a view in longitudinal section a device constructed inaccordance \vitl'r my invention, and

Fig. 2 is a transverse section taken on line E2--2 thereof.

Vt ith reference to the drawings, 10 indi cates a conical c, sing,formed at its apex vvitlr a tubular, externally threaded extension 11,and open and internally threaded at its base portion. A cap for thisbase portion is provided in the form of a disk 12 having an externallythreaded flange 13 integrally ilorlued on one thee, to engage thethreads oi? the base portion oi the casing. An air regulating disk 14-.is applied to the outer face of the cap, the latter and the dish beingcentrally apcrtured to receive an extension 15 Of a valve casing 16. Theextension cylindrical and ot a diameter to closely lit the opening ofthe disk 14, and a rehilced threaded portion 17 is formed on theextension to enter the opening of the cap, said opening beingslightlysmaller than that of the disk. i .s a result a shoulder 18 is formed onthe extension 15 to bear against the cap and to bind the latter betweenthe shoulder and a nozzle 19 which applied to the threaded portion 17and inclosed within the casings. The cap and disk ll are each tliorn'ledwith air shift openings 20 and 21 respectively and designed to registeror to be lapped by rotation of the disk, a handle being provided uponthe disk for that purpose. A coil spring en circled about the extension1.5 and bears against the etl e casing 16 and the disk ll the .to retainthe latter seated. The valve casings, extension 1% and nozzle 19 areformed with alined bores 2a which are also in alincinent With the centerof the casing and nipple ll. The bore of the valve casing opens intoachambe. and a valve seat 26 is formed at the juncture thereof, engagedby a needle valve 27. A lateral branch 28 oil the valve casing is:torrned to extend into a receptacle 29 to contain Water, a flange andnut arrangement 30 being provided to secure this device to saidcontainer.

lln use, the intake manifold of an internal combustion engine may bedrilled and tapped to receive the nipple 11. The con taincr 29 issupplied with Water, and the needle valve 27 adjusted to open position.The disk 14 is rotated by means of the handle to cause the openings 20and 21 to register. It Will be obvious that owing to the partial vacuumproduced in the manifold during the normal operation of the engine,Water will be drawn up through the branch 28 into the chamber 25 andthrough he bore 24. Owing to the fine aperture of said here a spray willbe formed and with a certain proportion of air admitted through theopenings 20 and 21 will enter the manifold and mix with the fuel vapor.The relative pro portion of Water and air may be varied by adjustment ofthe needle valve and dish 1% in the manner stated. While I haveillustrated and described 11])" invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts Without departing from the spirit ofthe invention or the scope of the appended claim.

Having thus described my invention, What I claim as new and desire tosecure by United. States Letters Patent is:

A device of the character described iii-- eluding a conical mixingchamber having its base portion open and a tubular extension on itsapex, a cap applied to the base portion having a central opening and aseries of air inlet openings, a disk having a central opening andaseries of openings applied to the cap, a valve casing, an extensionthereol, to enter the central opening of the dish: a threaded portion onthe extension to enter the central opening or the cap, a nozzle appliedto the threaded portion, a coil spring encircling the extension andbearing against the casing and disk to retain the latter in seatedposition, a handle on the disk for rorating the same, a valve in thecasing to control passage of nniterial through the nozzle. a branch ofsaid casing, and a receptacle to receive said branch.

In testimony whereof I allix my signature in presence of two witnesses.
